Izitena eziKhawulezayo eziBalaseleyo zeeFurnaces ze-AOD - Iintlobo, iiNzuzo kunye nezicelo

Isithando somlilo se-AOD (Argon Oxygen Decarburization) sisixhobo esiphambili sokwenza intsimbi engagqwaliyo kunye nentsimbi ekhethekileyo ye-alloy. Iindawo zokucoca i-AOD zinobushushu obuphezulu kakhulu, ukujikeleza kobushushu obunamandla, ukugqwala okunamandla kwe-alkaline slag, kunye nokukrala koomatshini. Ezi meko zinzima zokusebenza zenza izitena ze-AOD ezirhabaxa zibe zezona zibalulekileyo ezisetyenziswayo kwizityalo zentsimbi. Ukukhetha iintlobo zezitena ezifanelekileyo ezirhabaxa kwandisa ngokuthe ngqo ubomi benkonzo ye-furnace, kunciphisa iindleko zokutshintshwa ezirhabaxa, kwaye kuphucula imveliso iyonke yokwenza intsimbi.

Ukuba ufuna izisombululo ze-refractory layers ezihlala ixesha elide nezingabizi kakhulu kwiinqanawa ze-AOD, ukuqonda iintlobo zezitena ze-AOD refractory eziphambili kubalulekile. Apha ngezantsi siza kwazisa ngezitena ze-refractory ezisetyenziswa kakhulu nezisebenza kakuhle kwiilinings ze-AOD furniture.

Izitena ze-magnesia chrome ezibotshelelweyo ngqo zezona zinto zendabuko nezithembekileyo ze-lining ze-AOD furnitures. Zenziwe nge-magnesia exutywe ngobunono obuphezulu kunye ne-chrome ore ngokusebenzisa i-sintering yobushushu obuphezulu, ezi zitena zine-porosity ephantsi, uxinano olukhulu, kunye nokumelana okubalaseleyo kwe-slag. Zimelana ngokugqibeleleyo nokukhukuliseka kwe-slag yentsimbi ye-alkaline kunye noxinzelelo oluqhelekileyo lobushushu, oluqheleke kwiinkqubo zokucoca ze-AOD. Zilungele iindawo zesitshixo ezigugileyo kubandakanya umgca we-slag ye-AOD furniture, indawo ye-tuyere kunye ne-lining yokusebenza eludongeni olusecaleni, ezi zitena ezirhabaxa zithintela ngokufanelekileyo ukuqhekeka kwe-lining kunye nomonakalo wokungena.

Izitena ze-calcium zeMagnesia, ezaziwa ngokuba zizitena ze-dolomite refractory, ziye zaba zezona ndlela zithandwayo zokulondoloza indalo endaweni yezitena ze-chrome ze-magnesia. Ezi zitena zingenazo i-chromium engcolisayo, zinamandla aphezulu obushushu kunye nokumelana ne-alkaline slag ephezulu. Icandelo le-calcium oxide linokufunxa i-sulfur kunye nokungcola kwintsimbi enyibilikisiweyo, nto leyo ephucula kakhulu umgangatho wentsimbi engagqwaliyo. Uninzi lwabavelisi lusebenzisa ezi zitena kwiibhothi zesithando se-AOD, ii-linings ezisisigxina kunye namacandelo odonga lwangaphambili, zilungelelanisa ngokugqibeleleyo nemisebenzi yokwenza intsimbi eqhubekayo ixesha elide.

Izitena ze-magnesia ezicocekileyo kakhulu zenzelwe iindawo ezishushu kakhulu nezinobushushu obuzinzileyo zee-oven ze-AOD. Ngomxholo wokungcola okuphantsi kakhulu kunye nesakhiwo esincinci, zinika amandla angaqhelekanga oomatshini kunye nokumelana nomthwalo obushushu obuphezulu. Ezi zitena ezishushu kakhulu nezinobushushu obuphantsi zihlala zisetyenziselwa ii-linings eziphezulu ze-oven kunye nee-levels ezincedisayo zesakhiwo, zibonelela ngokhuseleko oluzinzileyo kunye nokunciphisa utyalo-mali lwezinto ezishushu ngokubanzi.

Kutheni Ukhetha Izitena Zethu Eziyingcali Ze-AOD Refractory?

Njengomvelisi wezitena ezinganyangekiyo ze-AOD, silawula ngokungqongqo ukukhethwa kwezinto eziluhlaza kunye neenkqubo zemveliso. Zonke izitena zethu ezinganyangekiyo ze-furnace zinokumelana okuhle kakhulu nobushushu, ukusebenza okunamandla okulwa nokugqwala kunye nobomi benkonzo ende. Sinikezela ngezitena ezinganyangekiyo ezisemgangathweni nezilungiselelwe wena ukuze zihambelane neemodeli ezahlukeneyo ze-furnace ze-AOD kunye neemeko zokusebenza kwemizi-mveliso. Iimveliso zethu zinceda iifektri zentsimbi ukunciphisa ixesha lokungasebenzi kwezixhobo, ukunciphisa iindleko zokulungisa kunye nokwandisa iingenelo zemveliso.

Iingcinga Zokugqibela

Iindawo ezahlukeneyo zeefeni ze-AOD zifuna izinto zezitena ezichaseneyo nezirhabaxa. Izitena ze-Magnesia chrome, izitena ze-dolomite kunye nezitena ze-magnesia ezicocekileyo kakhulu zigubungela zonke iimfuno zokusebenza kunye nezisisigxina zokwenza intsimbi ye-AOD. Ukuze ufumane izisombululo zefeni ze-AOD ezirhabaxa nezisemgangathweni ophezulu, zive ukhululekile ukuqhagamshelana nathi ukuze ufumane iikowuteshini ezenzelwe wena kunye nesikhokelo sobuchwephesha sobuchwephesha.
